    Notes: Abstract Soft-X-ray and extreme ultraviolet spectroheliographs carried by the OSO-7 (Orbiting Solar Observatory) have been used to record the development of XUV emission associated with a flare of importance 1b on August 2, 1972. Spatial resolution was 20″ and spectral resolution was adequate to select emission lines originating within well-defined ranges of electron temperature between 5 × 104 and 30 × 106K. The data show that heating only the pre-existing coronal material adjacent to the flare site cannot account for the soft X-ray emission measure observed during the event. The flare emission originating at T e ⩽ 2.3 × 106K exhibits an impulsive component coincident with an impulsive microwave event. This radiation appears to coincide spatially with Hα radiation emitted at that time and is centered on the neutral line separating magnetic fields of opposite polarity. One soft X-ray-emitting feature, estimated to have an initial electron temperature of 2–10 × 106K, forms during the impulsive phase immediately over the Hα flare. A second, arch-like feature observed at wavelengths near 1.9 Å and estimated to have T e≅30 × 106K is located approximately 35000 km above the Hα event. Both regions have lengths of about 27000 km but transverse dimensions small compared to the spatial resolution of the spectroheliograph, i.e., less than 14000 km. The region with highest electron temperature exhibits the greatest stability in position. This region cools to approximately 10 × 106K in 6 to 12 min which is compatible with cooling by conduction to the chromosphere. The best association with a dark surge is found in an emission line of Fe xiv.

    Notes: [Auszug] FOR the past four years a very simple form of tide-predicting machine, the invention of Captain A. Inglis, the harbour-master, has been in use at Port Adelaide for the construction of the yearly published tide tables. The tides at Port Adelaide are rather peculiar in their behaviour, this being ...

    Notes: [Auszug] ALONG the north-west coast of Australia the tidal wave, flowing in from the Indian Ocean, produces at most places a large rise and fall. At Port Darwin the mean spring range is about 24 feet, but the range is sometimes as much as 30 feet. A tide gauge of Lord Kelvin's pattern was set up here by ...

    Notes: [Auszug] THE accompanying photograph (Fig. 1) represents the side of a steel bar. The bar was first marked by a punch in the way shown, and the punch marks were afterwards completely filed out. The side was then polished and the bar pulled in a testing machine beyond the elastic limit of the material. ...

    Notes: Abstract Studies of the vaporization onset associated with heat flow are used as a tool to probe the superfluid thermohydrodynamics during entropy transport. Onset-flux-density data of the heat flow suggest that the normal fluid viscous force dominates during entropy transport from a single source (strip) to bulk He II over a layer of thickness 10 −4 cm (upper bound) or less.

    Description / Table of Contents: Zusammenfassung Alle Hauptnerven des Mund- und Rachennervensystems wurden kontrolliert reseziert. Erst wenn die rückwärtigen Rachennerven zerschnitten werden, nehmen die Insekten wesentlich mehr Nahrung zu sich. Solche Insekten versuchen längere Zeit zu fressen. Wenn sich während des Fressens der Vorderdarm füllt, wird keine Nahrung an den Mitteldarm weitergegeben und sein Vorderende ist der letzte Teil, der sich vollständig ausdehnt. Nach Durchtrennung der rückwärtigen Rachennerven sind alle Teile des Vorderdarms offen-sichtlich mehr gedehnt. Eine solche erhöhte Nahrungsaufnahme tritt aber nicht ein, wenn die Nahrung relativ ungünstig ist. Das Abbinden des Kropfes verursacht beim nachträglichen Fressen keine übermäßige Ausdehnung des Vorderteiles. Die Nahrungsaufnahme hat keinen Unterschied im Körpervolumen zur Folge und das Durchtrennen des ventralen Nervenstranges bleibt ohne Einfluß auf die nachträglich aufgenommenen Nahrungsmengen. Das vergrößerte Darmvolumen wird durch Kollaps des Luftsackes kompensiert.
    Notes: Abstract During the course of a meal by insects with an empty gut, food is held in the foregut and the midgut remains empty. The last part of the foregut to fill is the extreme anterior end of the crop, and stretch receptors in this region control the amount eaten. Cutting the posterior pharyngeal nerves isolates these receptors from the frontal garglion and results in hyperphagia pharyngeal nerves isolates these receptors from the frontal garglion and results in hyperphagia during one meal. On unfavourable food, when smaller amounts are eaten, distension of the foregut is not involved in regulating meal size. Feedback from receptors in the body wall is not important in regulating meal size; most of the increase in gut volume resulting from feeding is taken up by the collapse of the air sacs so that there is little or no change in the body volume.
